Rafael J. Wysocki 1516d9fa63 PM / core: Clear the direct_complete flag on errors ... commit 69e445ab8b upstream. If __device_suspend() runs asynchronously (in which case the device passed to it is in dpm_suspended_list at that point) and it returns early on an error or pending wakeup, and the power.direct_complete flag has been set for the device already, the subsequent device_resume() will be confused by that and it will call pm_runtime_enable() incorrectly, as runtime PM has not been disabled for the device by __device_suspend(). To avoid that, clear power.direct_complete if __device_suspend() is not going to disable runtime PM for the device before returning. Fixes: aae4518b31 (PM / sleep: Mechanism to avoid resuming runtime-suspended devices unnecessarily) Reported-by: Al Cooper <alcooperx@gmail.com> Tested-by: Al Cooper <alcooperx@gmail.com> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Cc: 3.16+ <stable@vger.kernel.org> # 3.16+ Signed-off-by: Rafael J.
